Motion of vortex lines in quantum mechanics
Iwo Bialynicki-Birula, Zofia Bialynicka-Birula, Cezary Sliwa
Exact analytic solutions of the time dependent Schrodinger equation are produced that exhibit a variety of vortex structures. The qualitative analysis of the motion of vortex lines…
Localization of Eigenstates & Mean Wehrl Entropy
Karol Zyczkowski
Dynamics of a periodically time dependent quantum system is reflected in the features of the eigenstates of the Floquet operator. Of the special importance are their localization p…
Operational Time of Arrival in Quantum Phase Space
Piotr Kochanski, Krzysztof Wodkiewicz
An operational time of arrival is introduced using a realistic position and momentum measurement scheme. The phase space measurement involves the dynamics of a quantum particle pro…
Quantum Anti-Zeno Effect
Maciej Lewenstein, Kazimierz Rzazewski
We demonstrate that near threshold decay processes may be accelerated by repeated measurements. Examples include near threshold photodetachment of an electron from a negative ion,…
